UNITED STATES PATENT OFFICE.

JOHN E. CULVER, OF LOS ANGELES, CALIFORNIA.

SCRAPER.

To @ZZ whom it may concern:

Be it known that I, JOHN E. OULVER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Scrapers, ofwhich the following is a specification.

This invention relates to scrapers and the object of the invention is toprovide a device which may be attached to a two wheeled scraper in whichthe scraping blade and all appurtenances are supported by the two wheelsof the scraper, the device when attached to the two wheeled scraperpreventing the vibrations andy varying strains on the scraping bladefrom being imparted. to the tongue. This affords the advantage, in thisrespect, of a four Wheeled scraper when the device is attached, and yetdoes not render the scraper useless as a two wheeled scraper but leavesit complete and operable if desired as a two wheeled scraper when thedevice is removed.

Further objects and advantages will be brought out in the followingdescription.

The accompanying drawings illustrate the invention, and referringthereto :hFigure 1 is a plan view ofthe device applied to a two wheeledscraper, the scraper being shown completely in detail. Fig. 2 is -a sideelevation of what is shown in Fig. 1.

1 designates scraper wheels mounted on shaft 2, from which is hung thescraper 3. Extending forward from shaft 2 are frame bars 4 which areunited by bolts 5. The device which is adapted to be connected to thetwo wheeled scraper in place of the rigid tongueconsists of a gooseneck6 comprising two bars is fastened by bolts 7 to the bars 4. 8 is a frontaxle with wheels 9. The hounds 10 extend back and are connected by bolt11 with the rear end of the tongue 12, the tongue 12 extending forwardover the axleS and being supported by a chain 13 connected to a hook 14on the tongue 12, the other end of the chain 13 being connected by aspring 15 with the upper end of an eye bolt 16. The eye bolt 16 isconnected by a chain 17 with a hook 18 fastened by a clamp 19 to thegooseneck 6. The eye bolt 16 is an upward extension of the king-bolt 20and thus the distance Specification of Letters Patent.

end of goooseneck 6 and 'under the'head of the king-bolt 20.

In operation the spring 15 permits the tongue 12 to swing verticallywithout imparting jerks to it. I/Vhen the device is attached to bars 4any side vibrations or jars of the scraper are transmitted bythe bars 4to the goose-neck 6 and are dissipated at the front trucknl. e.,wleels9, axle 8 and associated parts and thus there is no side vibration ofany moment imparted to the tongue 12, thus securing the advantage inthis respect of a four wheeled scraper in that the necks of the team arerelieved from strain caused by lateral jerks of the tongue. In swingingaround, the chain 13 is constantly effective in sustaining the weight oftongue 12 on account of the eye bolt 16 being in line with the If thebolt 16 were not in line with the king-boltat all times then the chain13 would be slack at certain positions of the tongue which would allowthe tongue to drop.

In the present invention the object is to provide a device which may beapplied to` two wheeled scrapers by removing the rigid tongue of thescraper which will relieve the teams as much as possible from anyunnecessary work and from injurious effects tending to physically impairthe efliciency of the team and yet enable the scraper, upon the.

removal of the device, to -be used as a two wheeled scraper in workwhere the extra length of the scraper with the attachment applied wouldrender .the scraper impracticable for use.

What I claim is In combination with a two wheeled scraper in which thescraper and all its appurtenances are carried by the two wheels thereof,of a device adapted to be attached to the IOO scraper in lieu of therigid tongue of the my hand at Los Angeles California this 5th scraper,which consists of a, gooseneok deday of November 1906.

taehably fastened to the frame of the two Wheeled scraper, a trucksupporting the JOHN E' CULVER' 5 front end of the gooseneek, and a tongue con- In presence ofneeted to the truck. 4 GEORGE T. HACKLEY,
